“Every Sound You Can Imagine”

REVIEW Art is in the air at City Hall, thanks to Bill Fontana’s "Spiraling Echoes" installation. In contrast, an ambitious exhibition at New Langton Arts explores the visual properties of musical pieces. Curated by Artforum contributor Christoph Cox, "Every Sound You Can Imagine" is rife with inkjet or offset prints of compositions  Morton Subotnick’s smudgy pencil jottings are an exception. A hefty percentage of works avoid standard notation to create sight-based sonic suggestions. To glean from just one small segment or wall, devoted to late-1990s works: Ryoji Ikeda’s Variations for Modulated 440hz Sinewaves is wonderfully nauseating in its op art effect, the score for Signal’s Lines conjures clouds in the sky, and William Basinski’s Shortwavemusic suggests the jagged lines of a seismograph or Richter scale.

Splicing songbooks to fuse Mendelsohn to John Lennon and Yoko Ono, the collage aesthetic of Hodges’ A Line Drawn in the Dark is, along with a piece by Steve Roden, one of the more inventive works here. The late Bruce Conner’s Untitled (music) has an effect similar to Will Yackulic’s recent experiments in drawing with a typewriter, while his contemporary, Wallace Berman, mines language and numeric systems. Downstairs, Christian Marclay’s video, Screenplay, sets many of these free-thinking compositional concepts into motion.

EVERY SOUND YOU CAN IMAGINE Through March 28. Tues.Sat., noon6 p.m. New Langton Arts, 1246 Folsom, SF. (415) 626-5416, www.newlangtonarts.org
